Defenses | Hints Grey Goo Guide

Last update: 11 May 2016

Focus your defenses. If there are two access paths to your HQ, find out where they meet and build a wall there. If the HQ is on big flatlands, block off access routes. Do not build walls around the entire HQ, especially if it is located in the middle of a desolate area. Instead, focus on several key points. The less spots there are to defend, the easier and more effective the defenses will be. If you can decrease their numbers, do that, even at the cost of moving fortifications away from the HQ.

Use walls and turrets in your defense system. The Beta may change the contents of their turrets, at will, whereas the Humans have turrets for all sorts of needs. Put them up alongside the walls, in the spots that are the most exposed to the enemy attack. Even one turret is better than no defenses at all.

Defend the HQ itself. Occasionally, a single unit may fight its way through fortifications and approach the HQ. IT does not wreak much havoc, but it is irritating and, in the worst case scenario, it attacks harvesters. It is for such situations that you could leave several turrets at the HQ. Apart from that, key structures also need to be defended with turrets, against air raids. In case of larger air raids, you may not be able to knock off all of the planes so, it is better to have an additional AA defense.

Use units for your defenses. Stationary defenses are good, up until artillery, or a gap in fortifications appears. Always keep a quick response unit at hand, capable of fighting both ground and airborne units. It is especially useful in situations, in which the enemy attacks the base from the direction, from which you expected no attack.

Use patrols in your defenses. Thanks to issuing an order to patrol, you will not need to keep an eye on each defending group. Also, it allows you to guard strategic passages, without the necessity to block them off. The only condition is that you determine reasonable routes for your patrols and regularly reinforce the ones, which have already been attacked by the enemy.

Use buildings in your defenses. At the beginning of the game, all of the buildings are difficult to destroy. Attack strength of units is low and the enemy forces are small. Later on, the enemy units become stronger and special demolition attacks will also be used. In spite of that, at any point into the game, you can also try using buildings in the form of fortifications. Build a Small Hub or a factory so you can block, or narrow, the passage to your HQ. The upside of this strategy is that you impede the progress of the enemy forces, or make it completely impossible. The downside is that you may have problems leaving the HQ. Therefore, you should use this tactic with moderation, so you do not make things more difficult.
